Facts and fables about straighteners
These straighteners have an aluminum body, insulated rollers and are made with a location calibration and a scale at the tension knob for fine tuning.
The units here are called wire straighteners, but are in fact wire benders. A unit with three rollers can only bend the wire. When used at a wire coming from a spoll you can in fact straighten the wire by bending it in the opposite direction. In case of wire coming from a drum the function of these units is to bend the wire in such way that the wire will not wobble when it comes out of the torch but curve out in one direction. Mainly when using aluminium from drums this can be a big problem. When it comes to the position of the unit at the welding installation, we stronly recommend to mount it at the entrance of the wire feeder.
